A side door window regulator may fail causing the window to stop working, in some eases falling into the door. Replacement of the failed regulator will be required to correct this concern.

Rear window regulator broke in the down position. You can hear the motor trying to move the window when you hit the button, but nothing happens. Part had to be replaced at the expense of $240

I have to replace 3 window regulators-front right driver's side 1 yr ago, 6 mos later the front passenger's side and about 6 months later the left rear passenger side. The driver's side went first, then the front passenger and lastly the left rear window. The costs of each repair was about $240.00 each at a non BMW, foreign car repair shop.

Rolled down rear window on my BMW 325i and hear a loud pop like breaking glass. Opened the door up and sure enough it was the window regulator that was broken on my car with 46K miles. BMW should be forced to repair this under a recall.

I have had to replace the passenger regulator twice and the driver side once... Not a very well engineered design if you ask me.

I have 3 windows motor/actuator replaced at various times. First it was my rear passenger window that won't go up or down at 45K miles. Then it was my passenger side(front) window followed by the driver side window. All three window motor regulator was replaced and cost of repair was high. BMW should have a recall re these issues.

The back regulators were both replaced along with the passengers before 55,000 miles by previous owner. I have now replaced the drivers at 70,000 miles for $390 Dec 2011.

Bought the car used and the window was open 1 inch only to find out that the regulator was faulty. Mechanic (whom I trust) says this is common in this car. Based on service record on CarFax,the rear window regulator was replaced at 35,000 miles.
